After the introduction of the Facebook Home feature, a new level of user-focused integration for Android devices, Fortune has published an interview with Mark Zuckerberg, CEO of Facebook, in which he discusses a number of topics, including the rivalry between Apple and Google in the mobile handset market.

Last week, it was noted that Samsung is going to usher in a new “store-within-a-store” concept inside Best Buy stores to compete the Apple Shops, which are located in many locations of Best Buy for several years.

Today Nuance announced a new mobile advertising platform called ‘Voice Ads’ to bring its Siri-like functionality into mobile advertising. The general concept of the new platform, which is available as an SDK for advertising companies, is to let users engage in a two-way, interactive conversation with a mobile ad and ask questions about the advertised product in a Siri-like manner.

Apple has long been a partner of Best Buy at special departments "Apple Shop" in many retail stores of electronics, but a new report from Geek.com indicates that Apple shops will soon joined by similar Samsung stores, along with the upcoming Galaxy S4 that serves as an incentive for the first phase of shops rollouts.

As Pocketgamer reports, this week Apple spoke with developers at the Game Developers Conference about providing support for an official iOS game controller. Last year Apple was rumored to have a game controller in the pipeline for iOS devices, but no such product has yet been released. The report notes:

The United States Patent and Trademark Office published an Apple patent application (via AppleInsider), which offers the possibility of using a flexible display in iPhone or in other mobile device with transparent cover as glass tubing or other form. The display would be able to cover the edges and backside of the device, even to make a more visible area.

As The Wall Street Journal reports, Apple has acquired indoor location positioning company WifiSLAM for around $20 million. Apple has confirmed the acquisition deal, but declined to share any details on its plans for the company. The report said:

While Apple has earned much praise for its iPhone design aesthetic, it also has received criticism for durability problems, with many users experiencing the issues after dropping their smartphones onto hard surfaces.

In the fifth-generation iPod touch and iPhone 5 Apple began using sapphire crystal in order to cover the rear camera of the devices, providing superior scratch resistance and durability. Apple notes:

While Android and iOS might appear poised to lock up the smartphone market for good, it is worth looking at the history of the smartphone market to understand just how quickly fortunes can change. In 2005, the market was dominated by Palm, Symbian and BlackBerry. However, by the following year all three had ceded control to Microsoft as the new market share leader. 2008-2010 saw BlackBerry stage a comeback to assume the #1 position before eventually giving way to the upstart Android platform in 2011. The only key player in the current smartphone market never to have owned the market share lead, interestingly enough, is iOS.
